Hello Sato,

as I wrote you via e-mail, You can cross the gate, pulling the wire with your hands,  and go through the spot, both on foot or by an off-road vehicle (only for a stretch). You can't get with a vehicle in the Fantasia and Sala degli Specchi areas, for the will of the owners, because the noise of the car can disturb their animals. 

That said, you can climb, you can picnic and also you can have a bath in the river.

Have a nice time in Bronte Blocks!
